Kitchenaid Under Counter Ice Maker

4 posts in this topic

I have an undercounter Kitchenaid Ice Maker...model KUIS15NRH SS.  The way it looks to me the water reservoir fills and then water starts to circulate over the freezing plate to create a sheet of ice.  When the proper thickness has been achieved, the ice sheet drops down to a heated grid which melts the sheet into cubes and drops into the bin.

The problem is, sometimes the ice sheet does not release from the freezing plate and a new cycle to create ice by recirculating water from the reservoir starts.  When the circulating water tries to go over the freezer plate, it hits the old ice sheet still on the freezer plate and the water dribbles down into the ice bin.  The water circulation pump continues to pump emptying the resivor because the  water went down into the ice bin.

Does it sound like a common problem?

I've cleaned the unit several times....we don't have real hard water.

I'm assuming the freezing plate has a control that heats up or turns off allowing the ice sheet to melt slightly thus slide down to the grid.  Could the problem be in the control of the freezing plate?

The problem will either be the hot gas solenoid valve or the evaporator thermistor (or thermostat on older units).  If the units fails to go into defrost, then the problem is the thermistor.  If it goes into defrost but it can't loosen the slab, replace the hot gas solenoid.

Thanks Exalted One.... I think I'll go with the thermisor first...  I appreciate your feedback

This 80 page manual on these ice machines from Whirlpool might address this problem....;)
